A multi-directional positioning metal member welding apparatus according to claim 1, wherein Two sides of each of the two guide rails (401) are provided with a circular hole five, and the interiors of the opposite two circular hole fives are connected with the same adjusting screw rod (402) through bearings, one side of the welding tool frame (1) is provided with two screw rod motors (403), the driving end of the screw rod motor (403) and one end of the adjusting screw rod (402) are fixedly connected with a belt wheel, and the exteriors of the two belt wheels are drivingly connected with the same belt (404).

3. A multi-directional positioning metal member welding apparatus according to claim 2, wherein The welding workbench (2) is fixedly connected with a limiting seat (5) on the upper side, and two sides of each of the two limiting seats (5) are provided with two circular sliding holes, and the interiors of the plurality of circular sliding holes are slidingly connected with guide cylinders three (7).

4. A multi-directional positioning metal member welding apparatus according to claim 3, wherein One end of each of the two guide cylinders three (7) on the same side is fixedly connected with the same positioning sliding seat (8), one side of each of the two limiting seats (5) is fixedly connected with an electric driving rod four (9), and the driving end of the electric driving rod four (9) is fixedly connected to one side of the positioning sliding seat (8).

5. A method of using a multi-positioning metal piece welding apparatus, using a multi-positioning metal piece welding apparatus as claimed in claim 4, characterized in that, Comprise the following steps: Step one, when positioning and welding the metal piece body (6), first place the metal piece body (6) on the welding workbench (2), and then start the screw rod motor (403), the screw rod motor (403) drives the adjusting screw rod (402) to move the clamping plate (413) on the screw rod nut sliding seat (405) to one side of the metal piece body (6) to be positioned; Step two, then start the electric driving rod one (407), move the horizontal moving plate (409) to the side of the metal piece body (6) through the electric driving rod one (407), and the two horizontal moving plates (409) are oppositely moved to preliminarily clamp and position the metal piece body (6) on the two sides of the exterior; Step three, then start the electric telescopic rod (414), move the positioning roller (437) on the lifting sliding plate (415) to one side in the metal piece body (6), according to the welding angle of the metal piece body (6), adjust the angle of the angle adjusting track (418) through the adjusting motor one (417), and adjust the angle of the clamping tool frame (425) through the adjusting motor two (423), and in the adjusting process, the clamping tool frame (425) is located at the center position of the welding angle through the angle positioner (426). Step four, after the adjustment is completed, start the electric drive rod two (420) driven adjustment slider (419) so that the clamping tool frame (425) to the welding angle of movement, while starting the electric drive rod three (429) driven two-way tooth bar (428) movement, two-way tooth bar (428) driven linkage gear (432) rotation so that open and close the branch (431) open until the positioning roller (437) and metal piece body (6) to be positioned surface contact, so that the horizontal support seat (434) on a plurality of positioning roller (437) on the inside of the metal piece body (6) multiple side clamping positioning.
